GAS-BURNER;

SPECIFICATION forming part of Letters Patent No. 756,155, dated March29, 1904. Application filed December 18, 1896. Renewed August 11,1903.-Seria1No. 169,080 (No model.)

To all whom it may concern:

Be it known that I, HENRY BRYANT, a citizen of the United States, and aresident, of Aransas Pass, inthe State of Texas, have invented a new anduseful Improvement in Gas- Burners, which is made and usedsubstantially,

as set forth hereinafter and as shown in, the accompanying drawings, inwhich Figure 1 is anelevation of the burner as in use. Fig.- 2 isthesame in section.

The object of this invention is to produce a burner suited to produce anilluminating-flame ofacetylene gas and to use the same for such purpose;and the invention consists in forming a burner with two jet brancheswith outlets at a suitable distance apart andprojecting from them forburning, so that jets of gas will issue and gather about them an envelopof air carried along and strike together at an angle of nearly ninetydegrees and spread into a beautiful flame in burning, and in Variousdetails to facilitate the manufacture and use of same.

Fig. 1 shows an external view, and Fig. 2 a

sectional view, of a burner made with-these improvements in one form.The base B is made to attach to a branch of a service-pipe A and haswithin it a chamber or space for a body of loose cotton C or othersuitable material for checking the flow of gas and reducing itspulsations to auniform motion. From this chamber spread two arms Dat anangle of about eighty degrees or thereabout. These arms D are arrangedso that they can be bored out with small drills, which will go inside.of-

the lower edge of the base B, as illustrated in dotted lines in Fig. 2.At suitable distances the arms D bear cross-tubes E at such angles thattheir upper ends will approach each other at an angle of about ninetydegrees. The cross-tubes E are arranged to be bored out with smalldrills from the outer ends, using very fine calibers for the jet-outletsat the upper ends and larger for the outer portions, into which areset-screws H to close the tubes. The tubesE are arranged at suitabledistances apart, so as to gather about the jets of gas envelops of aircarried with the gas smoothly and so that when they reach a proper pointthey will strike together fairly and spread into a beautiful flame Ffrom the gas and air carried with it in burning. The'ends of theburner-arms E E are made conical at their ends and'have roundoutlet-holes for the gasjets, arranged to carry air by frictionalcontact as a moving envelop, so as to cause mixture for thoroughcombustion by the two jets and their envelops striking andminglingtogether at a distance from the burner-points, so as ,to preventdeposit ofcarbon on the points and so the air will sweep away any chancedeposit. The extreme sharp ends of the cones around the outlet-holes arecutoff, so

the air passing along them to envelop the gas will come in contact justbeyond the end to avoid inducing a carbon deposit thereon. The

gas is thus emitted from the two burner-tips 7 having circular taperingorifices, so as to form fine jets of gas tending to form inverted conesdirected obliquely upward toward each other so as to impinge on eachother at a considerable distance above the tips to form a flame out ofcontact with the substance of the tips, so as to form aclearance-spacebetween the orifices and extending a distance below them,and so that a current of air will be drawn by suction along each of thetips, so as to sweep the conical point of the tip from any chancedeposit thereon.

Various modifications may be made in this. Fig. 3' shows one such, inwhich the arms D bear elbow-joints D and these bear burnertips E, withholes in their ends arranged to throw gas-jets to meet at the properdistances and angles to form the flame.

I claim- 1. In an acetylene-gas burner having abody B with arms Dbearing tubes with small externally-truncated conical tips with roundoutlets in their ends at a distance apart, formed soas to leave asurface at the extreme end of the tip between the orifice and the outertapering walls, arranged todeliver jets of gas which will gatherenvelope of air about them and strike together at an angle of nearninety degrees for burning. ii

2. A burner for acetylene gas, having two branches set at an angle toeach other with externally-truncated conical points, formed so as toleave a surface at the extreme point between the orifice and the outertapering walls, arranged to throw jets of gas together for burning at adistance from said points, and draw a current of air converging to theend of each cone, to prevent deposit of carbon on the tips.

3. In a burner the combination of two burner-tips, havingexternally-truncated conical ends, formed so as to leave a surface atthe extreme end of the tip between the orifice and the outer taperingwalls, arranged obliquely upward and each having an exceedingly-smallorifice opening from its apex, the tips being directed toward each otherwhereby the jet of gas emitted from each tip impinges upon the other jetat a considerable distance above the tips to form the luminous flame outof contact with said tips and little surface is formed at the tips toheat the gas as it emerges and receive deposits of carbon.

4:. In a burner the combination of two burner-tips havingexternally-truncated conical ends, provided with small apertures openingthrough the apexes of said conical ends, formed so as to leave a surfaceat the extreme end of the tip between the orifice and the outer taperingwalls, arranged obliquely upward and directed toward each other, wherebyall of the jet of gas emitted from each tip impinges upon the other jetat a considerable distance above the tips to form the luminous flame outof contact with said tips and pre vent carbon deposit, and aclearance-space is formed between the orifices of the burner-tips andextending to some distance below them.

5. An acetylene-gas burner having a body with arms bearing tubes withsmall externallytruncated conical tips with round outlets in their ends,set a distance apart, formed so as to leave a surface at the extreme endof the tip between the orifice and the outer tapering walls, andarranged to deliver jets of gas which will gather envelops of air aboutthem and strike together at an angle of near ninety degrees for burning,substantially as set forth.

6. In a burner the combination of two.

burner-tips having externally-truncated conical ends provided with smallapertures opening through the apexes of said conical ends, formed so asto leave a surface at the extreme point between the orifice and theouter tapering walls, arranged obliquely upward and directed toward eachother whereby all the jet of gas emitted from each tip impinges upon theother jet at a considerable distance above the tips to form the luminousflame out of contact with said tips and prevent carbon deposit, and aclearance-space is formed between the orifices of the burner-tips and.extending some distance below them.
